Three screws at the rear and two clips in the middle are a no-brainer, but two hooks at the front are a problem. Hooks are made of plastic and are installed into the frame, and they go into rectangular holes in the trim panel (right against number 5 on the diagram). Can't really see nor feel which way they're angled (space is pretty tight), and can't locate this part on realoem, either - it's in some obscure place.

This is how the hook looks like from inside the frame (was able to get the phone into the opening and point it [somewhat] the right way:

Google is of no help, unfortunately - a lot of people are installing subwoofers, but nobody seems to be removing them

So, which way do I pull what to take the trim panel out without breaking anything?
